What could have prevented the Silver Bridge collapse?

The designers believed they had found an answer. The solution is found in the material utilized for the eye-bars. The American Bridge Company created a special heat-treated carbon steel for use in the Silver Bridge's construction. This new steel would allow the bridge's individual components to withstand additional stress. It was assumed that once under way, traffic would be sufficient to sustain a constant temperature of this metal.

However, this assumption was wrong. During its initial years, traffic on the bridge was not enough to maintain adequate temperatures. So, during severe storms, such as those produced by hurricanes or heavy snowfall, the components of the bridge could lose significant weight due to wind erosion or plowing. When this happens, even a structure as strong as the Silver Bridge will eventually fail.

The cause of this failure was determined by investigators later. They found that all six sections of the bridge were missing some or all of their top chords. This showed that the force of the wind was able to remove the bridge's supports completely. Since the bridge was designed to stay up even without support, it must have been that one of its components failed long before the actual collapse occurred.

Investigators also discovered that several of the remaining components were damaged by corrosion. This too was probably the result of the force of the wind against the structure.

What was the silver bridge made out of?

Steel The Silver Bridge was the first in the United States to employ a "eyebar link" suspension system. The eyebars were two inches thick and resembled huge automotive wrenches. They were placed side by side on top of the bridge's main beam and were connected by four links. As the vehicle crossed over them, the links would pull against each other, causing the wheels at the ends of the beams to roll freely.

The system was invented by George Selick, who also designed the Lincoln Highway Bridge across the Missouri River in Hastings, Nebraska. This bridge used steel trusses instead of concrete piers as support for its decking, which gave it greater load-bearing capacity. It was opened just five months after the Silver Bridge and was an important factor in the collapse of the latter structure. The two bridges had very similar designs and standards were dropped to allow them to be interchangeable as crossing points for auto traffic.

Silver Was Once One Of America's Most Popular Metals

In addition to its use in construction, silver was also employed in industry. In fact, before the advent of aluminum, it played an important role in the manufacturing process. For example, it was used to make electrical contacts inside vacuum tubes that powered early televisions and radios.

How was the Silver Bridge Suspension Bridge built?

The Silver Bridge was the first eye-bar suspension bridge to be built in the United States. The bridge's eye-bars were chained together in pairs. A massive pin ran through the eye, connecting one piece to the next. Each chain link was made up of two 2" x 12" bars joined by an 11" pin. The bridge was painted gray.

The Silver Bridge was completed in 1913 over the Ohio River near Wheeling, West Virginia. It had a main span of 1,200 feet (365 m) and stood 70 feet (21 m) above the river. The bridge was designed to last at least 100 years but might have been expected to fail after only 50 years or less. It is estimated that it carried about 10,000 vehicles a day when it collapsed.

The cause of the collapse has never been determined with certainty. Some factors that may have contributed include heavy traffic, poor design, and lack of maintenance. However, many questions remain unanswered including why there were no fatal accidents among the drivers or passengers on either side of the bridge when it collapsed.

There have been several theories proposed about what happened to the vehicle that was driving on the wrong side of the road at the time of the collapse. Some experts believe that he or she may have tried to swerve to avoid a dog that had escaped from a nearby farmhouse. This would have put considerable stress on the vehicle's front end and may have caused it to turn sharply toward the opposite side of the road.

What kind of steel was used for the Brooklyn Bridge?

The American Bridge Company, which won the contract for the project, chose to employ eyebars instead of steel wire cables like those used in iconic suspension bridges like the Brooklyn and Golden Gate. The eyebars utilized were long steel plates that were 2 inches thick with a 12-inch face and varied in length from 55 to 44 feet. They were bolted at both ends with gussets between each pair of bolts to prevent them from pulling apart under tension.

Brooklyn Bridge had 110 of these eyebars in all. Each one is made up of two flat plates joined together by four bolts spaced evenly along their lengths. The whole structure is then painted black to help reduce heat loss through radiation into space.

This type of bridge construction is known as "ribbed" bridge building because there are no vertical members (i.e., girders or trusses) connecting the horizontal deck beams. Instead, the individual segments of the bridge are tied together with horizontal rails called "eyebars".

When complete, the bridge was considered innovative at the time because it was the first major suspension bridge made entirely out of steel. Before its construction, many people believed that true suspension bridges must contain some material in the form of wires or cables to support the load of the traffic crossing it. The Brooklyn Bridge proved this theory wrong.

In addition to being strong, the bridge was also flexible enough to be moved if needed.

What was the Silver Bridge disaster?

The Silver Bridge was a 1928 eyebar-chain suspension bridge called after the color of its aluminum paint. The Silver Bridge collapsed under the weight of rush-hour traffic on December 15, 1967, killing 46 persons. Two of the victims' bodies were never discovered. The incident became known as the "worst single loss of life in American history up to that time."

The collapse occurred during a heavy snowfall across much of Ohio. Winds up to 50 miles per hour and drifts as high as 30 feet contributed to the deaths of those aboard the bridge. It is believed that this combination of factors caused the span to buckle near the center.

The Silver Bridge was one of three parallel bridges over U.S. Route 23 in Marshall County, about 20 miles west of Cleveland. It was opened just four months before the next-to-last fatal accident on another nearby bridge. The other two bridges remained open despite their age and condition. They are now used only by pedestrians and cyclists, who can cross the Ohio River by way of the Cleveland Metroparks Zoo Bridge or the West Shoreway Bridges. The zoo bridge is also used by vehicles during special events such as the annual Christmas Tree Lighting Ceremony by President Lyndon B. Johnson.

In 1987, the United States Congress passed legislation authorizing the construction of a new bridge over the site of the old Silver Bridge.
